Invest in the shares of other companies
With an investment trust your money is pooled with contributions from many other people and used to invest in a range of different securities such as stocks and bonds. If good decisions are made, your investment is likely to rise in value, in addition, you get access to a much wider, and more diversified, portfolio of investments more easily than you could hold on your own.
The value of your investment can go down as well as up and you may not get back the full amount invested.
